The oil drain plug on a 2007 Chevrolet Silverado is located on the
bottom of the oil pan, which is situated underneath the engine. You'll need to get under the truck to access it. It's usually fairly straightforward to locate; it's a bolt, often slightly larger than other bolts in the area. However,
the exact location might vary slightly depending on the engine size (4.3L, 4.8L, 5.3L, or 6.0L).
Before you start, consult your owner's manual. It will have a diagram showing the exact location of the drain plug and other important maintenance points. This is the safest way to ensure you find the correct plug and avoid damaging anything.
